Answer

Reactants: $F_2$ and $HCl$. Products: $Cl_2$ and $HF$.

Work Step by Step

Reactants: In the reactants, we can identify 2 different compounds. - A molecule made of 2 yellow spheres. - A molecule made of 1 white sphere, and 1 green sphere. Since green spheres represent chlorine atoms, yellow spheres represent fluorine atoms, and white spheres represent hydrogen atoms: - 2 fluorine atoms: $F_2$ - 1 hydrogen atom, and 1 chlorine atom: $HCl$. Products: In the reactants, we can identify 2 different compounds. - A molecule made of 2 green spheres. - A molecule made of 1 white sphere, and 1 yellow sphere. Since green spheres represent chlorine atoms, yellow spheres represent fluorine atoms, and white spheres represent hydrogen atoms: - 2 chlorine atoms: $Cl_2$ - 1 hydrogen atom, and 1 fluorine atom: $HF$.
